A, need the owner's signature of construction engineering data, including design changes, negotiation records, contracts and visas, etc.

Second, the technical data of the steel structure industry should basically be signed by the supervisor, and all quality inspection data, experimental data and safety data should be signed by the supervisor.

3. Before the commencement of construction, the supervisor shall report to the owner the copy of the information contract, the commencement application report, the record of the blue prints.the design, the qualification of the construction unit (such as a copy of the business license), the construction permit, the subcontractor qualification submission form, the construction organization design (scheme) submission form, the construction organization scheme, the engineering materials, components and equipment submission form, etc.

Four, construction engineering data signature order:

1, divided into construction unit → supervision unit → construction unit → other units.

2. In contact order. Whoever contacts first will sign first.

Five, in order to ensure the engineering quality and traceability of engineering quality, every working procedure should be recorded normally. Construction leader (team level), quality inspector (project ministerial level or company level), quality checker (supervisor level or owner level), quality supervisor checker (government supervision agency). The above is mainly aimed at the construction unit, supervision unit and construction unit, and other related units such as design and exploration are all company-level.
